IMPROVEMENT IN VENTILATING APPARATUS.

Specification forming part of Letters Patent N o. 168, 864, datedOctober 19, 1875; application filed June 5, 1875.

CASE A.

To all whom it may concern.-

Be it known that I, JOHN G. BATES, of Cold Spring, in the county ofPutnam and State of New York, have invented a new and useful Improvementin Ventilating Apparatus, of which the following is a specification:

The figure is a vertical section of a room to which my improvedventilating apparatus has been applied.

The object of this invention is to furnish an improved apparatus forventilating rooms by introducing any desired amount of fresh air in sucha way as not to produce a draft, and by which the foul air may beexpelled from the room, thus causing a circulation and keeping the roomthoroughly ventilated.

The invention consists in a horizontal pipe communicating with the outerair, and having a drum pierced with flues interposed between theregister and the hot-air flue, the said inletpipe being combined andcommunicating with a v'ei tical pipe, which delivers the air into theroom in a vertical column far enough above the heads of the occupants torelieve them from the bad effects of a draft.

A represents the walls, B the floor, and O the ceiling, ot'a room. D arepipes leading in through openings in the walls of the building, andwhich may pass beneath the floor B of the room or not, as may beconvenient, and open into pipes E, extending up along or within the wallof the room to such a height as will prevent the air from said pipesfrom blowing upon the occupants of the room, and thus exposing them to adraft. When the pipes E are within the wall of a room their upper partshould pass into the room and up a little way along the surface of .saidwall vertically, the part of said pipes within the room being coveredwithan ornamental bracket. As the air is conducted to the room throughpipe D it passes through a drum, S, which is pierced with flues andinterposed between the register and the hot-air flue, so as to allow thepassage of heated air therethrongh. The object of the drum is to heatthe freshair as it is introduced and before it is admitted to the room.In the ceiling of the room is formed an opening, 0,

leading into a drum or pipes, F, placed above the ceiling, which openingmay be covered with an open-work ornament to hide it. The pipes F leadout through openings in the walls of the building. Openings a mayalso beformed in the walls A ofthe room at anydesired height, for the escape offoul air. in the walls of the building are all covered upon the outsideof the walls by plates or hoods G, the edges of which incline inward, asshown in the figure, to prevent the entrance of cold air, while allowingthe foul air to escape free- 1y. The inletopenings of the pipes E andthe on tlet-openings for the foul air may be provided with valves, toenable the amount of air passing in and out to be regulated as requiredor the said opening may be covered with wiregauze or otherfinely-perforated material. The latter construction will render theventilator automatic in its operation. The inlet-opening for the pipes Dshould be protected by a hood, H, and should also be covered withwire-gauze to keep out the dust.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The inlet-pipe D, having a drum, S, pierced withflues, and located between the register and the hot-air flue, incombination with the vertical pipe E, which delivers its air into theroom vertically and above the heads of the occupants, substantially asdescribed.
